摘要
基于Kelvin碰撞单元和动力弹塑性时程分析,建立了相邻等高七层钢筋混凝土框架模型,从结构层间位移角、楼层剪力和碰撞力这三个方面,研究了在不同防震缝宽度工况下,楼层碰撞破坏对相邻结构响应的影响,探讨了在不同间距下结构碰撞响应的规律,为相邻结构抗震设计和防灾减灾提供合理的建议。
Based on Kelvin collision element and dynamic elastic-plastic time history analysis, the article established a frame model of reinforced concrete adjacent seven-layer, researched the influences of poun- ding damage on the adjacent structure response under different joint widths of anti-earthquake and the law of structure collision response under different distances from three different aspects of interlayer displace- ment angle, layer shears and pounding forces. The result can provide some reasonable suggestions for seismic design and prevention and mitigation of disaster.
